By smelling the gas . For an example: Like if there is a candle which is lit when we will blow we can smell
you eat cheese
by smell

You can observe gases in air by using techniques like gas sensors, which can detect and measure gas concentrations in the air without directly seeing the gases. These sensors often rely on physical or chemical reactions that occur in the presence of specific gases and produce measurable signals or readings. Advanced techniques like spectroscopy can also be used to indirectly detect and analyze gases in the air based on their unique interaction with light.
You can observe gases through indirect methods such as detecting their odor, measuring changes in temperature, or using chemical indicators that react in the presence of specific gases. These methods can help in identifying the presence and characteristics of gases without seeing them directly.
Site - seeing is roaming an area to observe attractions, sites, etc.
So that we may observe and react with our environment.
go sight seeing...all u have to do is pay for gas! =)
Gas Station, Bathroom, Other people, Restaurant
"Sin verte" = Without seeing you
When burning camphor, you will observe a white flame and a distinct aromatic odor. Camphor sublimes, which means it transforms from a solid directly into a gas, without passing through a liquid phase.
Yes, you are.
